DS3231 IIC RTC Module
The DS3231 IIC RTC Module is a highly accurate real-time clock module. It includes 32Kbit EEPROM and a 10-bit temperature sensor with a resolution of 0.25C.

The DS3231 IIC RTC module is a budget-friendly solution for precise timekeeping. This I²C RTC boasts exceptional accuracy and comes equipped with a temperature-compensated crystal oscillator and crystal. It also features a battery input, allowing it to maintain accurate time even during power interruptions.

By incorporating a crystal resonator, the device boasts improved long-term precision and fewer components needed in manufacturing. The ds3231 Arduino is also available in both commercial and industrial temperature ranges, conveniently packaged in a 16-pin, 300-mil SO format.

The IC can be further understood by referring to the attached DS 3231 datasheet.

product includes:
There are a total of two alarms set for different times of the day.
Output from the digital temperature sensor.
Sign up for Aging Trim.
The DS 3231 RTC features a 2032 Battery Holder.
The RTC is extremely precise and takes care of all timekeeping tasks.
The real-time clock accurately tracks various elements such as seconds, minutes, hours, date of the month, month, day of the week, and year. It takes into account leap-years and remains valid until the year 2100.
The I2C device Address for AT24C32 can be easily configured by using SMD jumpers on the PCB, specifically A0, A1, and A2.
An output signal that can be programmed to generate a square wave.
Input for maintaining continuous timekeeping using battery backup.
Reduce energy consumption to increase the duration of battery life.
